본 연구는 상업공간에 환경적 자극으로 설치된 미술품 색 계열이 방문객의 만족도에 미치는 영향과 그 영향 관계의 조절효과를 분석하고자 하였다. 이를 위해 환경심리학 분야의 매장환경 연구에 적용된 자극(Stimulate)-유기체(Organism)-행동반응(Response)의 SOR 모형과 이를 이용한 선행연구를 토대로 미술품 색 계열(S) -기분 및 공간 어메니티(O)-만족도(R)의 연구 프레임워크를 개발하였다. 실험은미술품의 색 계열에 대해 난색과 한색이 설치된 이미지를 제작하여 두 집단 간 응답자가 반응하는 만족도 차이를 조사했다. 회귀분석을 통해 검증한 결과 미술품 색계열은 난색(vs. 한색)이 설치된 경우 더 높은 방문객의 만족도를 유도한다는 것을발견했다. 또한, 이러한 영향 관계에 있어서 기분과 공간 어메니티 유형의 조절요인을 분석한 결과 미술품 색 계열의 난색(vs. 한색)이 주는 긍정적 기분을 평균보다더 높게 느꼈을 때, 공간 어메니티의 네 가지 유형 중 쾌적성과 심미성만을 더 높게 인지했을 때 각각 유의한 조절효과가 나타난다는 것을 발견했다. 본 연구 결과는 상업공간의 물리적 환경을 자극하는 미술품의 난색 계열이 한색 계열에 비해 방문객의 만족도에 더 긍정적인 영향을 미치고, 이것은 긍정적 기분 및 쾌적성, 심미성에 따라 강화된다는 것을 증명함으로써 기존 문헌의 이해를 추가하고 효과적인마케팅 전략에 유용한 시사점을 제공한다. This study attempted to analyze the effect of the color series of artworks installed as environmental stimuli in commercial spaces on the satisfaction of visitors and the moderating effect of the relationship. To this end, based on the SOR model of Stimulate-Organism-Response applied to burial environment research in the field of environmental psychology, and the preceding research using the SOR model, artwork color series(S)-mood and spaace amenity(O)-A research framework for satisfaction(R) was developed. In the experiment, an online questionnaire was conducted for domestic college students and graduate students by producing images with two conditions depending on the case where warm colors and cold colors were installed for the color series of artworks. As a result of verifying the difference in satisfaction of respondents corresponding to the two conditions through regression analysis, it was found that the warm color(vs. cold color) of the artwork color series induces higher visitor satisfaction. In addition, as a result of verifying the controlling factors of mood and space amenity variables in this relationship of influence, a significant moderating effect was found when the positive mood of warm colors(vs. cold colors) in the artwork color series was felt higher than the average. And, of the four types of space amenity, it was found that a significant moderating effect appeared when only comfort and aesthetics were measured as moderating variables. The result of this study proves that the warm color series of artworks that stimulate the physical environment of commercial spaces has a more positive effect on the satisfaction of visitors than the cold color series, and this is reinforced by positive mood, comfort, and aesthetics. It adds understanding and provides useful implications for marketing strategies for building an effective spatial image.
Ocean color products from the Korean Geostationary Ocean Color Imager (GOCI).
Wang, Menghua,Ahn, Jae-Hyun,Jiang, Lide,Shi, Wei,Son, SeungHyun,Park, Young-Je,Ryu, Joo-Hyung Optical Society of America 2013 Optics express Vol.21 No.3
<P>The first geostationary ocean color satellite sensor, Geostationary Ocean Color Imager (GOCI), which is onboard South Korean Communication, Ocean, and Meteorological Satellite (COMS), was successfully launched in June of 2010. GOCI has a local area coverage of the western Pacific region centered at around 36N and 130E and covers ~2500 2500 km(2). GOCI has eight spectral bands from 412 to 865 nm with an hourly measurement during daytime from 9:00 to 16:00 local time, i.e., eight images per day. In a collaboration between NOAA Center for Satellite Applications and Research (STAR) and Korea Institute of Ocean Science and Technology (KIOST), we have been working on deriving and improving GOCI ocean color products, e.g., normalized water-leaving radiance spectra (nLw(λ)), chlorophyll-a concentration, diffuse attenuation coefficient at the wavelength of 490 nm (Kd(490)), etc. The GOCI-covered ocean region includes one of the world's most turbid and optically complex waters. To improve the GOCI-derived nLw(λ) spectra, a new atmospheric correction algorithm was developed and implemented in the GOCI ocean color data processing. The new algorithm was developed specifically for GOCI-like ocean color data processing for this highly turbid western Pacific region. In this paper, we show GOCI ocean color results from our collaboration effort. From in situ validation analyses, ocean color products derived from the new GOCI ocean color data processing have been significantly improved. Generally, the new GOCI ocean color products have a comparable data quality as those from the Moderate Resolution Imaging Spectroradiometer (MODIS) on the satellite Aqua. We show that GOCI-derived ocean color data can provide an effective tool to monitor ocean phenomenon in the region such as tide-induced re-suspension of sediments, diurnal variation of ocean optical and biogeochemical properties, and horizontal advection of river discharge. In particular, we show some examples of ocean diurnal variations in the region, which can be provided effectively from satellite geostationary measurements.</P>
Low-Density Quantum Dot Molecules by Selective Etching Using in Droplet as a Mask
Jihoon Lee,Wang, Z M,Hirono, Y,Dorogan, V G,Mazur, Y I,Eun-Soo Kim,Sang-Mo Koo,Seunghyun Park,Sangmin Song,Salamo, G J IEEE 2011 IEEE TRANSACTIONS ON NANOTECHNOLOGY Vol.10 No.3
<P>We demonstrate low-density quantum dot molecules (QDMs) by selective etching using In droplets as a mask. Selective etching is performed with InGaAs QDMs buried underneath GaAs capping layer, on which In droplets are formed by droplet epitaxy using molecular beam epitaxy. During the chemical etching, the droplets act as a mask and QDMs underneath the droplets that only survive. Photoluminescence measurement from the selectively etched QDMs in mesa structures shows a much reduced intensity, which indicates low-density QDMs. This technique provides a simple and flexible method to attain low-density QDMs. The density can be easily modified by the control of the size and density of In droplets, which is suitable for single QDM spectroscopy and for their device applications.</P>
대학로 공연장 집적의 장소성과 관람 행동에 따른 공연성과에 관한 연구: 공연예술통합전산망(KOPIS)과 K-MEANS 군집 알고리즘에 기반으로

This study utilized KOPIS data to examine performance outcomes and pattern changes based on the behavior of ticket buyers, with a specific focus on the placeness of a performance theater agglomeration in Daehakro. To this end, we extended the theory of planned behavior to conceptualize the relationship between the placeness of Daehakro and the behavioral attitudes of ticket-buying audiences and developed a framework that incorporates the characteristics of performing arts products. Through exploratory data analysis of KOPIS aggregate extracts and k-means cluster analysis, we identified that the characteristics of ticket purchasers and performing arts products exert varying expected effects on the placeness of the university district. This finding provides important insights, serving as a predictor and determinant of attendance behavior.

In this study, an analysis was performed on the performance of the solar water heating system with geo-thermal heat pump for a detached house. This system has a flat plate solar collector (8 ㎡) and a 3 RT heat pump. The heat pump acts as an auxiliary heater of the solar water heating system. These systems were installed at four individual houses with the same area of 100 ㎡. The monitoring results for one year are as follows. (1) The average daily operating time of the solar system appeared to be 313 minutes in spring (intermediate season), and 135 minutes and 76 minutes in winter and summer respectively. The reason for the short operating time in summer is the high storage temperature due to low water heating load. The high storage temperature is caused by a decrease in collecting efficiency as well as by overheating. (2) The geothermal heat pump as an auxiliary heater mainly operates on days of poor insolation during the winter season. (3) Despite controlling for total house area, hot water consumption varies greatly according to the number of people in the family, hot water usage habits, etc. (4) The yearly solar fraction was 69.8 to 91.5 percent, which exceeds the maximum value of 80% as recommended by ASHRAE. So the solar collector area of 8 ㎡ appeared to be somewhat greater for the house with an area of 100 ㎡. (5) The observed annual efficiency of solar systems was relatively low at 13.5 to 23.6%, which was analyzed to be due to the decrease in thermal efficiency and the overheating caused by a high solar fraction.
